To take advantage of the SAN boot feature with a QLogic host bus adapter
(HBA) on an Oracle SPARC host, you must configure the HBA.
Before you begin
Before you configure the QLogic HBA, ensure that you complete the following tasks:
- Configured the HBA for static port binding.
- Configured and mapped the volume that serves as the SAN boot disk.
- Configured the LUNs for use with VERITAS Volume Manager with DMP.
- Mirrored the boot volume onto the discovered LUNs.
- Installed the correct level of FCode on your HBA. To find the correct level, see the supported
hardware list at the following website:
www.ibm.com/support
About this task
To configure
the QLogic HBA for SAN boot, use the following
steps:
Procedure
- Change to the OpenBoot prompt. For example, you might enter a command that is similar to the following command:
shutdown -i0 -g0 -y
Note: An ok displays for the prompt when
you are at the OpenBoot prompt.
- Type setenv auto-boot? false. This command specifies that the system will not reboot after a power failure or after you use
the reset command.
- Type setenv
use-nvramrc? true to enable
script interpretation.
- Type reset-all to
clear the system's registers.
- Type show-devs to
identify the device
aliases and the associated paths of devices that are connected to
the system. Write down the device alias of the first QLogic HBA.
- Select the HBA device by typing "/devicestring"
select-dev, where /devicestring is the
device alias string that you wrote down. The following command is an
example:
" /pci@1f,0/pci@1/QLGC,qla@4" select-dev
Note: A space exists between
the opening quotation mark and the forward slash.
- Type show-children and write down
the
WWPN, loop ID, and LUN of the boot device.
- Type WWPN yourwwpn loopid lun set-boot-id,
where yourwwpn is the WWPN associated with the
boot volume, loopid is the associated loop ID,
and lun is the associated LUN. The
following command is an example:
5005076812345678 80 0 set-boot-id
- Type reset-all.
- Type boot vx-disk –rv,
where disk is the name of your boot disk.
